4.2. FACILITY TYPE AND LINE CODE FOR USE WITH CLFI CODE
AMI or B8ZS can be identified from the circuit number, when the CLFI code is used. The facility type will have a Z
embedded in the facility type for B8ZS operation.
Example:
101 /T1ZF/CHCGILLADC0/CHCGILTFH01 (B8ZS)
The lack of a Z in the facility type below indicates the circuit is AMI.
Example:401 /T1/LVPKILRNDC0/RCFRILADW01 (AMI)
The facility type indicates the framing ordered by the customer when CLFI circuit identification is used.
An F in the facility type denotes ESF. Lack of the F denotes Superframe or D4 framing.
Example:
101 /T1ZF /CHCGILCLDC3/CHCGILYRH05 EXTENDED SUPERFRAME- B8ZS
401 /T1 /LVPKILRNDC0/RCFRILADW01 D4 FRAMING (Superframe)- AMI
